To all whom it may cor/teem: Be it known that I, HAianrT. .KRAKAU, ofCleveland, Cuyahoga county, Ohio, have invented a-new and useful RadialDraft-Gear,

of which the following is a full, clear, and exact description,reference being had to the accompany' g drawings, forming part of thisspecification, in whichlon itudinal section showing dated December-'1,1903.

. ster somewhat larger rear end of the bearin Figure 1 is a plan view ofa draft-gear embodying my. invention; Fig. 2 is a vertical elevation ofthe bolster thecenter casting to which the frame of the draft-gearispivoted; Fig. 4 is a side elevation ofthepiece which supports the okeandserves as part of theconnection of t e gear-rigging wit an endview'partly in section of the piece shown in Fig. 4; and Fi 6 is avertical cross-section .on the 'line -VI of Fig. 2'.-

1; ig." 3 is a side 1My invention is an'improvement on the radialdraft-gear for which Ihave already obtained Letters Patent Reissue No.12,178,

As shown in the drawings, 2, 2 representthe center-sills ofthe car, 3the end si 4' the bledy-bolster, and 5 the truck-bolster. At t einterpose-between thes'ills' a casting 6,

the. construction of which. is shown in -F1gs.

1 2v and It fills'the space between the SlllS being riveted or boltedthereto at its sides,'and;has at its forward end an open socketconstituted by; upper and lower flang 6 in which the rear. end of thegeari" frame is. set, "vertical holes being formed in the flanges toreceive the pin 7 on which the gear-rigging frame swings radially.Obviously the parts can be reversed, the socket being formed onthelendfof. the gearrigging and fitting a projection on thecast- 6 I mgv A The .draft-gear'frame 8 is preferably a castwhich fits in thesocket'6, being held therein by the pin 7. It also preferablyhasshoulders 6*" which may abut against the ends ofthe flanges16. Thesocket'is at theextreme forward end of the piecefi. i A A The pineholein the bearing-9 is made than the pin, so that the can abut against thebase of the socket an .transmit' -thereto the strains .of bufling; Theforward end ofjjthe supports t on: the line-II II of Fig. A

' may be the truck; Fig. 5 is [ilace where the center sills cross thebol-' frameis supported under the end-sill by'a carry-iron 10, and inthe frame is set the draft rigging 'roper, comprising a drawbar-shank11', a yo e 12 and spring mechanism and fol-' lowers (shown by, dottedlines).

.The draft-gear frame constitutes in efiect a swingin draft-beam whichcontains .and e longitudinally movable part of the draft rigging. .Ittherefore has end shoulders I) constituting stops'for the followers, anditmay have intermediate stops if desired. At the forward end of theframe it provided with filling pieces 0 at each side of t e shank of thedraw ar j To support the yoke and followers and also to afford means forconnecting the draft-gear frame to the truck, I employ a yoke-supportshown in detail in Figs. 4 and -5. .It consists preferably; of a casting13 having vertical flanges 14 adapted to receive and to be bolted to theside-plates of the franieby bolts 15, and having a middle portion 16'adapted to receive the yoke. It also has lipsv 16 bearing'against theinner surfaces of the side plates; and at its base it has preferably alongitudinal strengthening flange 17, and dependin lateral flanges orlugs 18 formed with bolt 'oles 19 to connect it with the guidingspring-rods 20 which are pTonnected pivotally thereto as shown in ig. 1.ably comprises a'r'o'd20 which is pivoted to Each of theseguiding-rodspreferthe yoke-support as above stated and extendstelescopically within a rear'piece 21 which extends forward preferablyin the manner'of a cage over the spring 22 and has a collar 23 inadvanceof the spring. The

rear piece 21 is connected by a pivot-pin 24 V with a link 25 hich isconnected by a pin 26 with the truck-bolster, the pins 24 and '26 beingset at) right angles to each other so as to afford a joint fiexi le intwo directions and thus adapted to provide for vertical as well ashorizontal relative motionbetween "the parts.. The draft gear frame istherefore capable of rising and falling relatively to the-truck and thetruck is allowed to rise and fall in relation to the car-bod withoutputtingany strain tion. The doubly upon the true connecilexiblejoint maybe at the forward end of the guiding connection insteadof the rear end,or such joint may be placed at both ends thereof.-

advantages of my invention in'respect. of the simplicity and strength ofthe device will be appreciated by those skilled in the art.
